CAN
Each CAN port is separate from the other oering dierent Node IDs and an independent baud rate.
Yet, they can be combined (connected together) via a parameter setting. When combined, each port’s
communications are received and sent out on the other port. e circuits are not isolated, sharing
the 1351 internal power supply and I/O ground (B−) reference.
• CAN 1 (pins 3 and 4): CANopen/11-bit
• CAN 2 (pins 5 and 6): J1939/29-bit
OUTPUTS — CAN
PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Port 1
NMT State
port_1_nmt_state
0x5490 0x00
0 – 127
0 – 127
Read Only Controller CAN NMT state:
0 = initialization
4 = stopped
127 = pre-operational
Node ID
Port_1_Node_ID
0x2000 0x01
0x01 – 0x7F (hex)
1 – 127 (decimal)
0x11
17
Displays the controller’s Node ID, in hexadecimal.
For example: 0x11 = 17d
Note: Setup/assignment is via the Curtis Software Suite™:
Launchpad, add a device.
Do not assign the same CAN Node ID to the 2 ports.
Baud Rate
Port_1_Baud_Rate
0x2001 0x01
125K – 1M (kbps)
0 – 4
125k
0
Sets the CAN baud rate for the CANopen Slave system:
0=125Kbps, 1=250Kbps, 2=500Kbps,
3=800Kbps, 4=1000Kbps.
Note that the 2 CAN ports can have different Baud Rates.
Heartbeat Rate
Port_1_Heartbeat_Rate
0x1017 0x00
0 – 4000 ms
0 – 4000
100 Sets the rate at which the CAN heartbeat messages are sent from
the CANopen (port 1) system.
Termination
CAN_1_Termination
0x3002 0x00
Off – Enabled
0 – 1
Off Enables the electronically controlled termination resistor (120 Ω)
for CAN Port 1.
This termination is internal to the 1351, no additional or external
hardware is required.
Port 2
NMT State
port_2_nmt_state
0x5491 0x00
0 – 127 (0 – 127 )
0 – 127
Read Only Controller CAN NMT state:
0 = initialization
4 = stopped
127 = pre-operational
Node ID
Port_2_Node_ID
0x2000 0x02
0x01 – 0x7F (hex)
1 – 127 (decimal)
0x12
18
Displays the controller’s Node ID, in hexadecimal.
For example: 0x12 = 18d
Note: Setup/assignment is via the Curtis Software Suite™:
Launchpad, add a device.
Do not assign the same CAN Node ID to the 2 ports.
Baud Rate
Port_2_Baud_Rate
0x2001 0x02
125K – 1M (kbps)
0 – 4
125k
0
Sets the CAN baud rate for the CANopen Slave system:
0=125Kbps, 1=250Kbps, 2=500Kbps,
3=800Kbps, 4=1000Kbps.
Note that the 2 CAN ports can have different Baud Rates.
